\section{Introduction}

With the volume of digital multimedia content increasing, the importance of fast and accurate retrieval methods for types of content is rapidly rising. In the past, keyword based systems were often adequate for retrieval but these keyword based systems are labor intensive. In this paper, we describe our attempt at implementing a heuristic for determining the likeness of 3d models to one another based on the 2009 paper by \citet{sun} We also evaluate any problems we came across during implementation and measure the performance of this heat kernel based method in both computation time and accuracy.
